I found 16 properties in Whittier, Ca with 2 or 3 bedrooms for rent. However, none of them met your rent criteria. Section 8, though a federal program, is administered at the local level. The best bet would be to contact the housing dept there to get a list of landlords or properties that are in good standing with the Section 8. According to the Whittier, Ca city website, Los Angeles County administers Section 8 for their area. Here is the website: http://www.lacdc.org/
I hope this is helpful.
